SensorTransmitter

Sensor Data FSK Transmitter based on RadioLib using SX1276 or CC1101

This project is closely related to BresserWeatherSensorReceiver

Use Cases

• Emulation of sensors for testing purposes
• Emulation of sensors while replacing the data with entirely different sensor values, e.g. using the manufacturer's temperature sensor protocol to display snow depth instead.
• Repeater (combined with receiver)

Supported Protocols

• Bresser 5-in-1
• Bresser 6-in-1
• Bresser 7-in-1
• Bresser Lightning
• Bresser Leakage
